This invention relates screens, and has for an obj 3 Claims.

to adjustable window ect to provide a screen adjusa'ble to windows of varying widths and embodying new and improved features of structure 5 for facilitating such adjustment.

A further object of the invention is to provide a window screen having sections each movable relative to the other, and both provided with slots in their approximate faces, said slots registering one with the other, with improved means carried by each of said sections slidable within the slots of the other section.

A further object of the invention is to provide a screen having frame sections each of said frame sections having an extension beyond the end i hereof, said extension carr ber, the shank of which ying a T-shaped memis inserted through a slot in the opposite frame member, with the head of said T sliding within the hollow part of said frame.

A further object of the invention is to provide a screen of sliding sections with improved means for connecting the sections together in sliding relation.

The invention, therefore, comprises two initially independent frames, the side rails of each of which is provided with a longitudinally extending slot, and each ci said frames having at the end thereof means for carrying a T-shaped engaging member, the head of which is located in the in terior of Jthe opposed frame member and the shank of which extends through the slot.

The drawing illustrates an embodiment of the invention and the views therein are as follows:

Figure 1 is a view of the screen in elevation partially opened,

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1,

Figure 3 is a transverse sectional view taken on line 3 3 of Figure 1,

line 4-4 of Figure 1,

Figure 5 is a transverse sectional view taken through the end member that shown at Figure 4, Figure 1,

of the frame opposite i. e. on line 5-5 of Figure 6 is a perspective view of the fastener,

and

Figure 7 is a perspective view of one end of one of the side rails showing in dott ed lines the connection of one of the cross rails thereto. l

Like characters of reference indicate corresponding parts throughou The adjustable window s t the several views. creen which forms the subject-matter of this application comprises two subsantially identical sections A and B. Each of these sections is made up of longitudinal rails 10 provided with slots ll extending throughout substantially their entire lengths.

As will be noted, especially from the sectional views of Figures 2 and 3, these longitudinal rails are hollow and a present well-known manner of construcing would be of sheet metal folded in the form shown, but it is to be understood, of course, that the material and the manner of making are no limitations upon the invention.

Extending transversely across between the rails 10 are end rails 12. These end rails l2, as shown 70 more particularly at Figure 4, are likewise hollow, although that condition is relatively immaterial, but also at present the indications are that this cross rail will be made of folded sheet metal but similarly without such limitation. ,I5

Opposite the cross rails 12 the sections are provided with cross bars 13, a cross-section of which is shown at Figure 5. These are also shown as being hollow and folded from sheet material, but such construction is only a matter of convenience.

In all of the several rails shown, the material as folded comprises flanges between which are located the screen material 14, and is secured therein by rivets 15. For rigidifying the frames, corner bra es or gussets 16 are provided, being 85 secured through the flanges of the several rails by means of rivets 15', which also secure the corners of the screen fabric.

It will be noted, especially from Figure 5, that the cross bar 13 is arranged so that it slides in 90 close proximity to the screen fabric of the other section, and while not actually touching said screen fabric, provides an interval of such attenuation as to prevent the passage therebetween` of insects. Each of the side rails 10 is provided 95 with an extension 17 beyond the cross bars 13, and this extension is provided with a short slot 18, shown more particularly at Figure 7.

A securing member 19 is provided of sheet material folded into T-form, as shown more particularly at Figure 6, with the head of the T located within the hollow side frames 10, with the shank of said member extending through the slots 11 and the slots 18. After passing through the slots 18, the ends of the shank are separated and bent down, as indicated at 20 in Figures l and 3, so that when the sections are placed together, and the ends of the T fastener bent over, the two sections are permanently but slidably interconnected as the head of the T will slide freely within the hollow of the side rails within the slots 11.

V/hile the several corners of the frame may be constructed in any approved manner, it is found desirable to attach the cross bar 13 by cutting away the iiange of the rail 10, as indicated at 21, in Figure '7, and forming a slot 22 under the bead of this side piece, so that the flange of the bar 13 may slip into this slot and abut against the cutaway end 21.

For attaching the end rails, the side rails 10 are provided with an extension 23, which covers over the otherwise exposed open ends of the cross bars, and with the rails 10 and 12 crossed and riveted by the corner reinforcing rivets 15.

In operation the two sections A and B, when drawn outwardly from the position shown at Figure 1, will cause the heads of the T connection 19 to slide within the rails 10 and along the slots 11, such slots terminating at such point that the two cross bars 13 will not pass each other, but will maintain the device as a unitary structure not separable, except by the releasing of the turn-downed parts of the T connections.

As it is considered desirable that such disconnection shall not be made, it is contemplated that these ends 17 and turn-downed parts 20 should be covered with solder or other owing metal. In this manner the device is constructed as a permanently interconnecting adjustable unit.

Of course, the adjustable window screen herein illustrated may be modified and changed in various ways without departing from the invention herein set forth and hereafter claimed.

1. An adjustable window screen comprising 10 and the shank freely sections having longitudinal rails each of which is provided with a longitudinal slot substantially uniformL throughout its length, and a connecting member carried by each of said rails, permanently and slidably xed within the slot of the coacting rail.

2. An adjustable window screen comprising similar sections, each section comprising a frame with longitudinally extending hollow rails sliding one upon the other, said rails being provided with longitudinal slots, extensions beyond the ends of said frames provided with perforations, headed connection members each having its head within the hollow of one of the longitudinal rails and extending through the longitudinal slot thereof and the perforations of the associated extension on the associated section, and upset upon the remote side of said extension.

3. An adjustable window screen comprising similar frames including hollow longitudinal rails, said rails having longitudinally extending slots communicating with the interior of the rails and in register each with the other, extensions beyond the ends of said frames, each of said extensions being provided with a perforation, a connecting member comprising a strip of material folded into T-form with the head located within the interior of one of the longitudinal rails, and the shank extending through the longitudinal slot thereof and the perforation of the associated extension of the associated section, and upset upon the remote side of said extension.
